Line segment QP¯¯¯¯¯¯¯¯ s the angle bisector of ∠PQR.
Line segment Modifying above upper Q upper P with bar s the angle bisector of angle upper P upper Q upper R .

Line segment QC¯¯¯¯¯¯¯¯ is the angle bisector of ∠PQR.
Line segment Modifying above upper Q upper C with bar is the angle bisector of angle upper P upper Q upper R .

Line segment AC¯¯¯¯¯¯¯¯ is the angle bisector of ∠PQR.
Line segment Modifying above upper A upper C with bar is the angle bisector of angle upper P upper Q upper R .

Line segment BR¯¯¯¯¯¯¯¯ is the angle bisector of ∠PQR.

To determine which line segment is the angle bisector of ∠PQR, we need to recall that an angle bisector divides an angle into two equal parts. The angle bisector will be the line segment that runs from the vertex of the angle (in this case, point Q) and divides the angle ∠PQR into two angles of equal measure.

Without the image to reference directly, we can make inferences based on the typical labeling and alignment of lines in geometry problems.

  1. Line segment QP would connect points Q and P, which might not necessarily bisect the angle unless it's specifically stated or illustrated.
  2. Line segment QC connects directly from Q to another point C. If C is positioned such that angles ∠PQB and ∠CQR are equal, then QC could be the angle bisector.
  3. Line segment AC connecting A and C does not originate from Q and therefore cannot be the angle bisector of ∠PQR.
  4. Line segment BR does not originate from Q either, so it also cannot be the angle bisector of ∠PQR.

In most cases, the angle bisector for the angle shown from Q to points P and R would be the line connecting Q to point C (if C is on the relevant bisector line affecting angle ∠PQR).

Thus, if QC divides the angle into two equal parts, line segment QC is the angle bisector of ∠PQR would be the correct answer, based on the common configurations of bisectors in angles with labeled points.
